Abstract
This study aims to elucidate the mechanism of driving nano/micro dielectric ceramics particles under the nano second pulse or DC electric field. The microstructure driving is affected by various electrical phenomena occurring at the same time such as surface potential, polarization, and electrostatic force. It makes the challenge to clarify the driving mechanism. A simple experimental system was used to observe the behavior of the ceramics nano particles and spherical micro ZrO2 particles in a nonaqueous solution under the electric field. The results suggested that the driving mechanism of the ceramics nano particles and ZrO2 particles under electric field was created by the combination of the electric image force, the gradient force and the contact charging phenomenon. We thus propose a method to control the micro/nano structure by using this motion control mechanism in further studies and application. Recent Publications 1.
